This invention relates to a carton for retaining a roll of sheetmaterial and dispensing lengths therefrom, said carton being formed froma single integral blank and provided with a cutting edge of novelconstruction formed from the blank itself for cutting desired lengths ofsheet material. More specifically, this invention relates to adispensing carton for retaining a roll of waxed paper 'andother types offrangible sheet materials from which suitable lengths of the sheetmaterial may be dispensed from the carton.

Hitherto it has been the common practice to provide dispensing cartonsof this typewith metal cutting blades afiixed to a free wall portion ofthe carton to provide a cutting edge for cutting lengths of sheetmaterial from the roll retained in the carton. The manufacture of suchcartons provided with metal cutting blades entailed considerable expensenot only on account of the cost 4 of the material involved, but also onaccount of the additional operations required in suitably aihxing themetal cutting blade to the carton. Furthermore, the use of metal cuttingblades was a source of possible injury to the user of the carton. Suchcartons also could not be disposed of or destroyed readily when empty onaccount of the metal cutting blade.

According to the present invention, the aforementioned difiiculties anddisadvantages have been fully overcome. A carton is providedwhich isformed from a single integral blank of cardboard and the like which issuitably out and scored to form a receptacle for receiving and retaininga roll of sheet material, one of the walls thereof being provided with acutting edge for sheet materials by providing the wall portion with acontinuous cut score extending the full. length of the wall portion, thewall portion being folded back along the cut score to position anexposed cut edge of the folded portion in oifset relation to thecongenetic cut edge of the wall portion, the folded-back portion beingadhered to the con tacted inner face of the wall portion.

Otherfurther details of th invention will be apparent from the followingspecification and appended drawings.

Referring to the drawings, Figure Lshows a carton formed from anintegral single blank shown in Figure 2 for retaining a roll of sheetmaterial and for dispensing lengths A oi the sheet material by cuttingsame against a cutting edge provided in the carton. The blank may beformed of any suitable material, such as cardboard and the like,suitably cut and scared to provide a receptacle portion for retainingthe roll of Figure 1, partly in i 90 of sheet material. formed byfolding the blank along score lines I and 2 to form a front'panei IS, abottom panel 15 and a rear panel it. These panels are provided withhinged end flaps indicated by numerals then folded over the ends of thereceptacle and adhered thereto in the position shown in Figure 1.

A cover is hingedly connected to the top panel l3 along a hinge line 4.The hinge line may be of any suitable construction, but it is preferredto use a hinge line having alternately arranged semi-circular cuts andcreased score lines as disclosed in Broeren-Patent No. 2,303,253November 24, 1942. The cover is formed of a closure panel l2 having endflaps l9. The closure panel normally extends in the same plane as thefixed top panel l3 and can be hinged upwardly in the position shown inFigure 4, whereby access to the receptacle may be had if necessary forgrasping the end A of the web of sheet material for dispensing purposes.A cutting panel In is hingedly connected to the closure panel alongscoreline 5. The cutting panel is provided with end flaps integrallyhinged thereto. These end flaps are indicated by numerals l1 and i8 andare adapted to. be folded back on themselves The receptacle portion isassasas line 40 is positioned in offset relation to the hinge scorelines 30 provided in the end flaps of the cutting panel l as clearlyshown in Figures readily cut by a pulling action on the end of" 8 and 9.When the panel portion 9 is folded back so as to hinge along the scorelines so, the cut edge of panel 8 will be offset in relation to thepanel in asshown in Figure 8. The cut score line is preferably formed byapplying the cutting knife to the outer face of the blank and pushingthe fibers toward the inner face of the blank, as shown in Figure 6,whereby a very sharp cutting edge 60 is formed in each of thecongenetically cut edges in the cutting panel I 0. As shown in Figure 8,the exposed edge of the panel portion ii has a sharp knifeedge contourso that the sheet material can be the web against the cutting edge inthe manner shown in Figure 1. The panel portion 9 also serves as areenforcing extension when it is folded back and adhered to the panel inand serves to stiffen the full length of the cutting panel so as toresist bending and distortion when the carton is used fordispensing'purposes. As shown in Figure 3, the cutting panel I0 isadapted to overlap the adjoining front wall l6 of the receptacle and thesheet material is passed for withdrawal from the roll between the frontpanel l6 and the overlapping cutting panel Ill.

We have found it advantageous to coat or 1m pregnate the exposed cuttingedge with an indurating material, such as molten sulphur, syntheticresins, waxes, lacquers, and the like, for stiffening the fiber materialof the blank at and adjacent the cutting edge, whereby a rigid cuttingedge is provided which will not soften in humid weather or become dullin use.

along score line 30 as shown in Figures 2, '7 and 8, and are adhered tothe overlapped flap portions. The cutting panel is provided with a cutscore line 40 which extends the full length of the panel IG and isintersected at the ends thereof by short slits 4i extending at rightangles thereto and terminating at the score lines 30.

In forming the cutting edge for the web of sheet material, the cuttingpanel in is folded ,back on itself on the score lines 35 shown inenlarged view in Figure 7 to assume the position indicated in Figure 8.The cut edge 60 of the folded back portion will then be positioned inoffset relation to the congenetic cut edge of panel I0.

The folded back portion .9, together with the hinged end flap portionsI! are glued or secured in any suitable manner to the overlapped innerface of the cutting panel 10. The end flap portions I1 and I8 are cut insuch contour as to coincide throughout their area when they aresuperposed. These superposed end flaps l1 and i8 are then folded overand adhered to the end flaps ill by an adhesive 19. as shown in Figure5, to form side ends for the cover in the relation shown in Figure 1. Itwill be noted that these side ends have a 3-ply thickness thus givingvery rigid ends. The broad features of the end flap construction arecovered in Sullivan et a1. Patent No. 2,314,849, March 23, 1943. Whenthe carton is produced by automatic machinery it is preferred to foldthe panel portion 9 and adhere it to the overlapped body of the blankprior to feeding the blanks to the automatic carton making machine.

An important feature of the present invention relates to the cuttingedge which is formed from the blank shown in Figure 2. The cut score Itis to be understood that the cutting edge construction, previouslydescribed, is not limited merous changes and modifications may also bemade embodying the principle of this cutting edge construction. Forexample, the relative positions of the score lines 30 and cut score lineAll may be varied to provide any desired amount of offset for thecutting edge in relation to the shear panel. Also if desired, the scorelines 30 and cut score line 40 may be reversed from the position shownin Figure 2 so that when panel portion 9 is folded back, the exposed cutedge of panel 10 will be offset in relation to panel 9, the free edgethereof providing the cutting edge.

Figures 10 to 15 show another type of dispensing carton constructionformed also from a single integral blank. The blank is suitably cut andscored to provide a front panel 50, a bottom panel 5|, a rear panel 52,a closure panel 53 and an extension panel 54. End flaps 55, 56 and 51are hingedly connected to the front, bottom and rear panels,respectively. Front panel 50 is provided with a cut score line 40extending the full length of the panel 50. The cut score line 40 isformed in the manner previously described in connection with the cartonconstruction shown the score line so to the cut score line 40, the cutedge 80 of panel 10 will be ofiset in relation to the cut edge of thefront wall 50, thereby providing a cutting edge for the end A of the webof sheet material.

In forming the carton from the blank as shown in Figure 11, the frontand rear panels are folded up at right angles to the bottom panel andtheir respective end flaps are superposed and glued together, preferablywith the end flaps 56 positioned intermediate the end flaps '1 and 55.The portions 58 of flaps 51 are adapted to be folded over the open endof the receptacle so formed. The cover 53 may then be folded over in theposition shown in Figure 13 and the extension flap 54 is then insertedwithin the receptacle. The web of sheet material is adapted to bewithdrawn from the carton between the front wall 50 and the insertedflap extension 54; The cutting edge may also be indurated in the mannerl.
